She drinks a lot of water and has consume milk of magnesia(ph value 10.5) before she feels comfortable again. State the pH values of water and blood and whether its acidic or alkaline.
The exothermic chemical reaction CO(g) + H2O(g) CO2(g) + H2(g) has Kc = 0.034 at 25°C. We currently have a flask containing all the components listed in this equation at equilibrium at 25°C. Subsequently, we will either (1) add some H2 to the flas..
